配置web.xml报错 Invalid content was found starting with element 'init-param'.

在搭建springmvc框架时，需要配置web.xml中的字符表编码过滤器
配置如下

 <filter>
	<filter-name>CharacterEncodingFilter</filter-name>
	<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
	<init-param>
		<param-name>encoding</param-name>
		<param-value>utf-8</param-value>
	</init-param>
	<init-param>
		<param-name>forceRequestEncoding</param-name>
		<param-value>true</param-value>
	</init-param>
	<init-param>
		<param-name>forceResponseEncoding</param-name>
		<param-value>true</param-value>
	</init-param>
	<filter-mapping>
		<filter-name>CharacterEncodingFilter</filter-name>
		<filter-pattern>/*</filter-pattern>
	</filter-mapping>
</filter>

结果报错其中的

CharacterEncodingFilter /* 报错‘cvc-complex-type.2.4.a: Invalid content was found starting with element 'filter-mapping'. One of '{"http://java.sun.com/xml/ns/javaee":init-param}' is expected’

后研究得知，错误原因为
根元素中的模式文件不对，
javaee只支持单个的config不支持filter-mapping，要换成 j2ee

即将模式文件

“http://java.sun.com/xml/ns/javaee”
改成
“http://java.sun.com/xml/ns/j2ee”

测试发现不报错。
